[原][C#.net]自定义控件中CollectionBase的使用集合编辑器

2009-11-02 17:50

最近研究自定义的控件，CollectionBase 真的是很好的东西，效果图如下

其中包括很多经典代码：怎么给List命名？怎么写name的重复报警等？怎么通过index或name找list等

部分代码网上找到，部分代码自己编写，总之还算完善，愿结识喜欢做控件的朋友共同探讨之~~

public class FieldItems : CollectionBase
{

        public FieldItems(PxAutoGenTxtPanel _pxAutoGenTxtPanel)
            : base()
        {

            // TODO: 在此处添加构造函数逻辑
            pxAutoGenTxtPanel = _pxAutoGenTxtPanel;
            //

        }
        private PxAutoGenTxtPanel pxAutoGenTxtPanel = null;
        PublicClass pubClass = new PublicClass();

public FieldItem this[int index]
{

            get
            {
                return (FieldItem)base.List[index];
            }

            set
            {
                base.List[index] = value;
                //this[index].FieldItems = this;
                //this[index].PxAutoGenTxtPanel = pxAutoGenTxtPanel;
                //this[index].Index = index;
